Use "effeminate" in a sentence
"For instance, the King James Version uses the term effeminate which is an offensive term to describe a man whose behavior, appearance or speech is considered to be more similar to that of females."
"It's the "unbecoming" part that leads me to associate the word effeminate with a degree of campiness that I don't believe applies to Renly and Loras."
"The adjectives and derivatives based on woman's distinctions are alien and derogatory when applied to human affairs; "effeminate" -- too female, connotes contempt, but has no masculine analogue; whereas "emasculate" -- not enough male, is a term of reproach, and has no feminine analogue."
